Heart attacks affect millions of people worldwide, yet successful resuscitation is achieved in only about 10% of cases. When the heart stops beating, medical professionals attempt to restore blood flow by performing chest compressions and assist the patient’s breathing through intubation or the use of a balloon pump to inflate the lungs. However, the optimal balance between these two life-saving measures, and how they influence each other, is not yet fully understood. Gaining a deeper understanding of this interplay could potentially increase the survival rate of patients undergoing resuscitation. It's crucial to minimize interruptions to the “artificial heart” function provided by chest compressions during resuscitation. However, completely neglecting breathing support would place the patient in even greater danger. Striking the right balance between chest compressions and ventilation is critical, yet challenging. Investigating the relationship between these interventions is a key step toward finding this balance.
